Having a problem with the confirmation e-mail running through Amazon SES.

I have no problem when my SMTP server is configured to a gmail account, but seem to when I change it make to my Amazon SES account. SES works fine for CiviMail and for other e-mail, so something about the format of the CiviEvent confirmation e-mail is messing it up.

I have PDF receipts turned off.

Here is the error message I get:

Failed to send data [SMTP: Invalid response code received from SMTP server while sending email. This is often caused by a misconfiguration in Outbound Email settings. Please verify the settings at Administer CiviCRM >> Global Settings >> Outbound Email (SMTP). (code: 554, response: Transaction failed: Illegal content disposition 'inline' in content type 'multipart/alternative'.)]
Any ideas? Where can I find the code that actually sends the CiviEvent confirmation e-mail?
